Background: While COVID-19 vaccination has been shown to reduce the risk of severe illness, its impact on the occurrence of persistent symptoms in patients with mild Omicron infection remains uncertain. Our objective was to investigate whether COVID-19 vaccination reduces the occurrence of persistent COVID-19-related symptoms 3 months after mild Omicron infection.
Methods: Multicenter prospective cohort study was conducted in Brazil between January 2022 and June 2023 when Omicron was predominant.

Rationale: Evidence about long-term sequelae after hospitalization for acute respiratory distress syndrome due to COVID-19 is still scarce.
Purpose: To evaluate changes in pulmonary, cardiac, and renal function and in quality of life after hospitalization for acute respiratory distress syndrome secondary to COVID-19.
Methods: This will be a multicenter case-control study of 220 participants.

Background: The long-term impact of hospitalization for COVID-19 on patients' physical, mental, and cognitive health still needs further assessment.
Objectives: This study aims to evaluate factors associated with quality of life and cardiovascular and non-cardiovascular outcomes 12 months after hospitalization for COVID-19.
Methods: This prospective multicenter study intends to enroll 611 patients hospitalized due to COVID-19 (NCT05165979).
Dengue is a viral disease transmitted by mosquitoes that has spread rapidly across all continents in recent years. There are four distinct but closely related serotypes of the virus that causes dengue (DENV-1, DENV-2, DENV-3, and DENV-4). In the present study, we evaluated temporal spreading and molecular evolution of dengue virus (DENV) serotypes.

Purpose: To assess the association between acute disease severity and 1-year quality of life in patients discharged after hospitalisation due to coronavirus disease 2019 (COVID-19).
Methods: We conducted a prospective cohort study nested in 5 randomised clinical trials between March 2020 and March 2022 at 84 sites in Brazil. Adult post-hospitalisation COVID-19 patients were followed for 1 year.

Introduction: The long-term effects caused by COVID-19 are unknown. The present study aims to assess factors associated with health-related quality of life and long-term outcomes among survivors of hospitalization for COVID-19 in Brazil.
Methods: This is a multicenter prospective cohort study nested in five randomized clinical trials designed to assess the effects of specific COVID-19 treatments in over 50 centers in Brazil.
